POWER TAKE-OFF.

Application filed. February 8, 1920. Serial No. 356,745.

To all whom it may concewi:

Be 1t known that we, BENJAMIN C. ZU- HARS and HARRY D. CLARKE, citizens of the United States, residing at Grand View Heights, Columbus, in the county of F ranklin and State of Ohio, have invented certain new and useful Improvements in Power Take-Offs; and we do, hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Thisinvention relates to new and useful improvements in power take-offs for trac tors or motor vehicles and has for one' of its objects the provision of means whereby gear of a transmission and used for driving machinery from the power source of the tractor or motor vehicle.

Another object of this invention is the provision of a housing for supporting the pulleyand power take-off shafts and which can be quickly and conveniently applied to a transmission and its housing and also position the pulley wheel at'such point that it can be easily belted to machinery for the purpose of driving the same.

A further object of this invention is the provision of a power take-off of the above stated character which may be cheaply manufactured or machinedand owing to its few parts may be easily and quickly assembled and installed on a tractor or motor vehicle.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangementofparts as will be hereinafter more fully described and claimed. For a complete understanding of our in vention, reference is to be had to the following description and accompanying draw-- ings in which: i I

Figure 1% is a detail sectional view illustrating a locking pin for theshifting rod.

Referring in detail to the drawings, the numeral 1 indicates a transmission housing having formed integrally with its rear end a differential hanger 2 and has secured to its front end a clutch housing 3. The transmission housing 1 has a transmission 4 located therein and the counter-shaft 5 thereof has journaled thereon an idle gear 6 continuously driven by said transmission 4, and which extends through an opening 7 formed in the top wall of said transmission housing 1'. The heretofore described parts form subject matter for co-pending applications.

A power take-off housing 8 is seated on the top of the transmission and clutch housings and is provided with a lateral flange 9 bearing caps 12 are adjustable within said openings from the exterior of the power take-off housing 8 and have bearings 13 therein to rotatably support the end of a power takeoff shaft 141., A shifting gear 15 is slidably secured to the power takebll' shaft 14: and is adapted to be nioreiil into and out of mesh with the idle gear 6 by a controllingmeans 16 thereby providing construction wherein the power take-off shaft can be driven by the transmission at at any time desired. hiloreorer the idler 16 being" continuously engaged with the transmission will quickly come to rest and consequently the shifting gear will not have to mesh with a free spinning gear. The controlling; means 16 include a rod 17 slidably mounted in the upper portion of the power take-oil housing 8 one extending exteriorly and rearwardly of said housing and provided with a handle 18. A fort; it) secured to the rod 17 and engag s a grooved collar 20 formed integrally with the shifting 15. The rod 17 is provided with spaced grooves 21 to be engaged by a spring actuated plunger 22 located in a socket of the housing 8 tor the purpose of locking the shiftino gear 15 into and out of mesh with the idle gear 6. The plunger 2L is held within the recess 25 by means of a plug which is th "cadet. into said recess from the erterior of the housing 8 providing a construction wherein the tension of the spring of said plunger 22 can be adjusted from the exterior of the housing 8.

A wall 25 is formed in the power take off housing 8 and is provided with an open ing 26 to permit the power take-off shaft 1 to extend therethrough and a lealnproof cap 27 is secured to said wall and is provioed with a packing 28 which engages the power take-off shaft 14 for the purpose of establishing a leak-proof connection between the shaft and the wall 25 This connection between the power take-off shaft and the housing 8 provides a lubricant compartment 29 in the forward end of said housing 8 adapt ed to be partially filled with lubricant by way of a port 230 closed by a removable plug 31.

miter gear 32 is secured to the forward end of the power take-off shaft 14: and is located in the cluu'nber 29 and has its hub 33 disposed agai. "he packing for the purpose of holding said packing; in place. .lt is to be noted that by adjusting the bearings 13 at each end of the power take-oil housing 8 will also adjust the hub 33 of the miter gear 3:2 against the packing thereby taking; up any wear that may have occurred in said packing.

A lateral branch 3-1}: is formed on the forward portion of the power take-oil housing 8 and l as communication with the cl'iaml ier 29 and has its end ha ed as illustrated at 35 and provided with an internal flange 36. An internal flange 8? is formed in the lateral branch 34- at a point of its formation to the housing 8 and is adapted to receive a flange 39 formed on'the inner end of acastin'g or from the spirit and scope sleeve 40 which is positioned within the lateral brunch hi and is provided with a flange ll which fits within the flange 36. An attaching thing- 42 is formed on the casting or slot; o 4-0 and abuts the flared end 35 of the lateral casting 54: an d is secured thereto by fasteners provic' a construction wherein the castii'ug or sleeve t0 may be easily and conveniently removed and rcplaced in said lateral branch 34,

Bearings id and 45 are located in the ends of the casting or sleeve 4L0 and rotatabiy support a pi-illey shaft h) which extends into the chamber and has :ezocured thereto a miter gear hat meshes with the miter so that said pulley shaft in is rotated by the pow r takeoff sl 6ft 1. The hub of the miter gear t? abuts Lll bearing ii- .vhile the hub 48 of a pulley i9 abuts the bearing 45 and said pulley is splined to the outer end of the pulley shaft 4:6 and is if her secured thereon by a nut 50 tin-ceded onto the end of said shat i adjusting" the nut on said shaft 4-6, the ii' in the bearings 45 and i l can be easil when up.

A lealeproof cap 51 is secured to the outer end of the casti or sleeve fish and is pro rided with a pacinng to prevent the escape of lubricant from the casting or sleeve.
